Description

本発明は、電動作業機等の電気機器および電気機器に装着される電源装置並びに電気機器と電源装置とからなる電気機器システムに関する。 The present invention relates to an electric device such as an electric work machine, a power supply device attached to the electric device, and an electric device system including the electric device and the power supply device.

電力により作動する電気機器には、機器本体の電源装着部に電池パック等の電源装置が着脱可能に装着されるものがある。例えば、電気機器としてのドリル、インパクトレンチ、インパクトドライバ、芝刈り機、集塵器および丸鋸盤等の電動作業機は、特許文献１に記載されるように、機器本体に着脱可能に装着される電池パックを有している。 Some electric devices that are operated by electric power have a power supply device such as a battery pack detachably mounted on the power supply mounting portion of the device body. For example, electric work machines such as drills, impact wrenches, impact drivers, lawnmowers, dust collectors, and circular saws as electric devices are detachably attached to the main body of the devices as described in Patent Document 1. I have a battery pack.

同種の電動作業機であっても、使用状況に応じて、電動モータの出力トルクが相違する複数のタイプがある。例えば、ボルト等の被駆動部材に打撃トルクを加えながら締め付け作業を行うインパクトドライバには、電動モータの定格電圧が１４．４Ｖのタイプと、１８Ｖのタイプがある。いずれのタイプのインパクトドライバにおいても、機器本体側の電源装着部と、電源装置である電池パックの着脱部との着脱機構の基本構造は共通化されている。電源装着部はその両側に設けられるガイドレールを有し、電池パックの着脱部はガイドレールのガイド溝に挿入されるガイドレールを有している。着脱機構を共通化すると、同じ電源装置である電池パックを、異種の電動作業機にも装着することができ、例えば、同じ電池パックを、インパクトドライバに装着することができるとともに、インパクトレンチにも装着することができる。 Even for the same type of electric work machine, there are a plurality of types in which the output torque of the electric motor differs depending on the usage situation. For example, there are two types of impact drivers, one with a rated voltage of 14.4V and the other with a rated voltage of 18V, for impact drivers that perform tightening work while applying striking torque to a driven member such as a bolt. In all types of impact drivers, the basic structure of the attachment / detachment mechanism of the power supply attachment portion on the device main body side and the attachment / detachment portion of the battery pack, which is the power supply device, is common. The power supply mounting portion has guide rails provided on both sides thereof, and the battery pack attachment / detachment portion has a guide rail inserted into the guide groove of the guide rail. By sharing the attachment / detachment mechanism, the battery pack, which is the same power supply device, can be attached to different types of electric work machines. For example, the same battery pack can be attached to the impact driver and also to the impact wrench. Can be installed.

このように、電動作業機等の電気機器の電源装着部と電池パックの着脱部の着脱構造を共通化し、同種の電動作業機において作動電圧が相違する複数のタイプをシリーズ化したり、異種の電動作業機にも同じ電池パックを装着することができるようにする場合には、機器本体の定格電圧と相違した異種電圧の電池パックが機器本体に装着されるのを防止するために、誤装着を防止するように構成している（特許文献２）。 In this way, the attachment / detachment structure of the power supply mounting part of the electric equipment such as the electric work machine and the attachment / detachment part of the battery pack is made common, and multiple types with different operating voltages in the same type of electric work machine are made into a series, or different types of electric work If the same battery pack can be installed on the work equipment, it should be installed incorrectly in order to prevent a battery pack with a different voltage from the rated voltage of the device from being installed on the device. It is configured to prevent it (Patent Document 2).

The rib 33 is located closer to the tip of the device body 10a than the protrusion 15.

一方、図４に示されるように、付加的な低電圧型電源装置としての電池パック２０ａの誤装着防止部２５の幅方向一方側には、切り欠き部３４が設けられている。電池パック２０ａのスライドレール２４を機器本体１０ａのガイド溝１４に挿入して電池パック２０ａを機器本体１０ａに装着すると、図８に示されるように、リブ３３が切り欠き部３４に入り込んで、電池パック２０ａは機器本体１０ａに装着される。このときには、着脱操作部３１は突き当て部１８に当接する。図８は機器本体１０ａの電源装着部１１ａに電池パック２０ａが装着された状態を示す。装着が完了すると、爪２８が係合溝１６に係合する。これにより、定格電圧１４．４Ｖの電気機器であるインパクトドライバ１に、１４．４Ｖの電力を供給することができる状態となる。 On the other hand, as shown in FIG. 4, a notch 34 is provided on one side in the width direction of the erroneous mounting prevention portion 25 of the battery pack 20a as an additional low-voltage power supply device. When the slide rail 24 of the battery pack 20a is inserted into the guide groove 14 of the device main body 10a and the battery pack 20a is attached to the device main body 10a, as shown in FIG. 8, the rib 33 enters the notch 34 and the battery The pack 20a is attached to the device main body 10a. At this time, the attachment / detachment operation portion 31 comes into contact with the abutting portion 18. FIG. 8 shows a state in which the battery pack 20a is mounted on the power supply mounting portion 11a of the device main body 10a. When the mounting is completed, the claw 28 engages with the engaging groove 16. Thus, the impact driver 1 is an electrical apparatus rated voltage 14.4V, a state in which power can be supplied to the 14.4V.

図５に示されるように、低電圧型電源装置としての電池パック２０ｂの誤装着防止部２５には、上述した切り欠き部３４が設けられていない。したがって、図９に示されるように、電池パック２０ｂを機器本体１０ａの電源装着部１１ａに装着しようとすると、電池パック２０ｂが所定の装着完了位置となる前に、機器側の誤装着防止部としてのリブ３３に、電源側の誤装着防止部２５のストッパ部２６が当接する。これにより、電圧１８Ｖの電池パック２０ｂの電源が定格電圧１４．４Ｖの機器本体１０ａに誤装着されることが防止される。図９は誤装着防止部２５のストッパ部２６がリブ３３に当接して、電池パック２０ｂが機器本体１０ａに装着できない状態を示す。このようにして、電池パック２０ｂの誤装着が防止される。 As shown in FIG. 5, the erroneous mounting prevention portion 25 of the battery pack 20b as a low-voltage power supply device is not provided with the notch portion 34 described above. Therefore, as shown in FIG. 9, when the battery pack 20b is to be mounted on the power supply mounting portion 11a of the device main body 10a, the battery pack 20b is used as an erroneous mounting prevention unit on the device side before the predetermined mounting completion position is reached. The stopper portion 26 of the erroneous mounting prevention portion 25 on the power supply side comes into contact with the rib 33 of the above. This prevents the power supply of the battery pack 20b having a voltage of 18V from being erroneously mounted on the device body 10a having a rated voltage of 14.4V. FIG. 9 shows a state in which the stopper portion 26 of the erroneous mounting prevention portion 25 comes into contact with the rib 33 and the battery pack 20b cannot be mounted on the device main body 10a. In this way, the battery pack 20b is prevented from being erroneously installed.

図２（Ｂ）に示されるように、低電圧型の機器本体１０ｂの電源装着部１１ｂには、図２（Ａ）に示した誤装着防止部としてのリブ３３が設けられていない。したがって、電池パック２０ｂを機器本体１０ｂに装着すると、電池パック２０ｂは着脱操作部３１が突き当て部１８に当接する装着完了位置まで移動し、電池パック２０ｂを機器本体１０ｂに装着することができる。装着が完了すると、爪２８が係合溝１６に係合する。これにより、定格電圧１８Ｖの電気機器であるインパクトドライバ１に１８Ｖの電力を供給することができる。 As shown in FIG. 2B, the power supply mounting portion 11b of the low-voltage type device main body 10b is not provided with the rib 33 as the erroneous mounting prevention portion shown in FIG. 2A. Therefore, when the battery pack 20b is mounted on the device main body 10b, the battery pack 20b moves to the mounting complete position where the attachment / detachment operation portion 31 abuts on the abutting portion 18, and the battery pack 20b can be mounted on the device main body 10b. When the mounting is completed, the claw 28 engages with the engaging groove 16. As a result, 18V of electric power can be supplied to the impact driver 1, which is an electric device having a rated voltage of 18V.

このように、機器本体１０ｂにはリブ３３が設けられていないので、図４に示される電池パック２０ａを機器本体１０ｂに装着することはできる。この場合は、定格電圧１８Ｖの電気機器に、１４．４Ｖの電力が供給されることになり、機器本体１０ｂの定格電圧は供給されないが、電気機器におけるモータ等に損傷が発生することは防止される。 As described above, since the rib 33 is not provided on the device main body 10b, the battery pack 20a shown in FIG. 4 can be attached to the device main body 10b. In this case, 14.4V of electric power is supplied to the electric device having the rated voltage of 18V, and the rated voltage of the device main body 10b is not supplied, but damage to the motor or the like in the electric device is prevented. To.

図３に示されるように、共用型の機器本体１０ｃの一方のガイドレール１２には、突出部１５よりも機器本体１０ｃの先端側に位置させて機器側の誤装着防止部（主誤装着防止部）としてのリブ３３ａが設けられている。リブ３３ａはガイドレール１２から機器本体１０ａの幅方向内方に突出しており、図２（Ａ）に示したリブ３３よりも突出寸法は長くなっている。 As shown in FIG. 3, one guide rail 12 of the shared device main body 10c is positioned on the tip side of the device main body 10c with respect to the protruding portion 15 to prevent erroneous mounting on the device side (main erroneous mounting prevention). The rib 33a as a portion) is provided. The rib 33a protrudes inward from the guide rail 12 in the width direction of the device main body 10a, and the protruding dimension is longer than that of the rib 33 shown in FIG. 2A.

一方、図６に示されるように、電圧可変型電源装置としての電池パック２０ｃの誤装着防止部２５には、リブ３３ａが入り込む切り欠き部３４ａが設けられている。電池パック２０ｃのスライドレール２４を機器本体１０ｃのガイド溝１４に挿入して電池パック２０ｃを機器本体１０ｃに装着すると、リブ３３ａが切り欠き部３４ａに入り込んで、リブ３３ａは誤装着防止部２５を回避して誤装着防止部２５には当接しない。そして、電池パック２０の着脱操作部３１が突き当て部１８に当接し、電池パック２０ｃは機器本体１０ｃに装着される。切り欠き部３４ａは誤装着防止部２５を切り欠くことにより形成され、電池パック２０ａに設けられた切り欠き部３４よりも幅方向に大きい。 On the other hand, as shown in FIG. 6, the erroneous mounting prevention portion 25 of the battery pack 20c as the voltage variable power supply device is provided with a notch portion 34a into which the rib 33a is inserted. When the slide rail 24 of the battery pack 20c is inserted into the guide groove 14 of the device body 10c and the battery pack 20c is mounted on the device body 10c, the rib 33a enters the notch 34a, and the rib 33a inserts the erroneous mounting prevention portion 25. Avoid contact with the erroneous mounting prevention unit 25. Then, the attachment / detachment operation portion 31 of the battery pack 20 comes into contact with the abutting portion 18, and the battery pack 20c is attached to the device main body 10c. The notch portion 34a is formed by notching the erroneous mounting prevention portion 25, and is larger in the width direction than the notch portion 34 provided in the battery pack 20a.

低電圧型の機器本体１０ｂの電源装着部１１ｂには、図２（Ａ）に示されるようなリブ３３が設けられていないので、電池パック２０ｃを機器本体１０ｂに装着することができる。このように、電池パック２０ｃは、低電圧型の機器本体１０ｂと、高電圧型の機器本体１０ｃのいずれにも装着することができる。 Since the power supply mounting portion 11b of the low-voltage type device main body 10b is not provided with the rib 33 as shown in FIG. 2A, the battery pack 20c can be mounted on the device main body 10b. As described above, the battery pack 20c can be attached to both the low-voltage type device main body 10b and the high-voltage type device main body 10c.

共用型の機器本体１０ｃには、機器側の誤装着防止部としてリブ３３よりも突出寸法が長いリブ３３ａが設けられているので、機器本体１０ｃに電池パック２０ａを装着しようとすると、図１０に示されるように、電源側の誤装着防止部２５のストッパ部２６がリブ３３ａに当接する。これにより、電池パック２０ａを機器本体１０ｃに装着することはできない。図１０は、ストッパ部２６がリブ３３ａに当接した状態を示す。 The shared device body 10c is provided with a rib 33a having a protrusion dimension longer than that of the rib 33 as an erroneous mounting prevention portion on the device side. Therefore, when the battery pack 20a is mounted on the device body 10c, FIG. As shown, the stopper portion 26 of the erroneous mounting prevention portion 25 on the power supply side comes into contact with the rib 33a. As a result, the battery pack 20a cannot be attached to the device body 10c. FIG. 10 shows a state in which the stopper portion 26 is in contact with the rib 33a.

電池パック２０ｂには切り欠き部３４ａが設けられていないので、機器本体１０ｃに電池パック２０ｂを挿入すると、誤装着防止部２５がリブ３３ａに当接する。これにより、電池パック２０ｂを機器本体１０ｃに装着することはできず、電池パック２０ｂの機器本体１０ｃに対する誤装着が防止される。 Since the battery pack 20b is not provided with the notch portion 34a, when the battery pack 20b is inserted into the device main body 10c, the erroneous mounting prevention portion 25 comes into contact with the rib 33a. As a result, the battery pack 20b cannot be mounted on the device body 10c, and the battery pack 20b can be prevented from being erroneously mounted on the device body 10c.

機器本体１０ｃにおける誤装着防止部としてのリブ３３ａは、一方のガイドレール１２に設けられているが、両方のガイドレール１２に設けるようにしても良く、突出部１５に機器本体１０ｃの前方に突出させてリブを設けても良い。いずれの形態においても、機器本体１０ｃに対応させて、電池パック２０ｃ、２０ｄの誤装着防止部２５には切り欠き部が設けられる。また、誤装着防止部２５のストッパ部２６が突出部１５に当接することで電池パック２０の移動を規制しても良い。 The rib 33a as an erroneous mounting prevention portion in the device main body 10c is provided on one guide rail 12, but may be provided on both guide rails 12, and the rib 33a protrudes forward of the device main body 10c on the protruding portion 15.

Are connected in parallel (FIG. 11 (A)). In this way, the battery pack 20c as the variable voltage power supply device supplies a predetermined voltage to the device main body according to the device main body to be mounted.

図６においては、電池パック２０ｃにそれぞれのスリット２９に突出して設けられた電源側端子が符号３０で示されているが、いずれか１つの電源側端子３０は、正極用の電源側端子４３ａ、４５ａに対応しており、それぞれの電源側端子は上下に分離されている。同様に、負極用の電源側端子４４ａ、４６ａは、他のいずれか１つの電源側端子３０に対応しており、それぞれの電源側端子は上下に分離されている。２つ正極用の電源側端子は共通（単一）のスリット２９に配置され、２つの負極用の電源側端子は共通（単一）のスリット２９に配置される。 In FIG. 6, the power supply side terminals provided in the battery pack 20c so as to project from the slits 29 are indicated by reference numerals 30, but any one of the power supply side terminals 30 is a power supply side terminal 43a for the positive electrode. It corresponds to 45a, and each power supply side terminal is separated into upper and lower parts. Similarly, the power supply side terminals 44a and 46a for the negative electrode correspond to any one of the other power supply side terminals 30, and the power supply side terminals are separated into upper and lower parts. The power supply side terminals for the two positive electrodes are arranged in the common (single) slit 29, and the power supply side terminals for the two negative electrodes are arranged in the common (single) slit 29.

図３においては、機器本体１０ｃ、１０ｄの機器側端子が符号１７で示され、上下に２分割された２つの機器側端子１７が示されている。２つの機器側端子１７の一方が正極用の機器側端子４３ｂ、４５ｂに対応しており、他方が負極用の電源側端子４４ｂ、４６ｂに対応している。 In FIG. 3, the device-side terminals of the device bodies 10c and 10d are indicated by reference numerals 17, and two device-side terminals 17 divided into upper and lower parts are shown. One of the two device-side terminals 17 corresponds to the device-side terminals 43b and 45b for the positive electrode, and the other corresponds to the power supply-side terminals 44b and 46b for the negative electrode.

図１１に示されるように、電圧可変型電源装置としての電池パック２０ｃに、３つの蓄電ユニットを組み込むと、電池パック２０ｃは低電圧型電源装置としての電池パック２０ｂの３倍の高電圧を出力する電圧可変型電源装置となる。電池パック２０ｃに設けられる蓄電ユニットの数は、図１１に示した２つに限られず、２つ以上の整数倍とすることができる。 As shown in FIG. 11, when three power storage units are incorporated in the battery pack 20c as a variable voltage power supply device, the battery pack 20c outputs a voltage three times higher than that of the battery pack 20b as a low voltage power supply device. It becomes a voltage variable type power supply device. The number of power storage units provided in the battery pack 20c is not limited to the two shown in FIG. 11, and may be an integral multiple of two or more.

図７に示される高電圧型電源装置としての電池パック２０ｄの誤装着防止部２５には、電池パック２０ｃと同様のサイズの切り欠き部３４ａが設けられ、さらに、着脱部２２ｄの後端側部には電源側の誤装着防止部（副誤装着防止部）としての突起部５１が設けられている。突起部５１は着脱部２２ｄの先端部から後端部に向けて上向きに傾斜して着脱部２２ｄから突出している。一方、図３に示されるように、共用型の機器本体１０ｃの突き当て部１８には、突起部５１が入り込んで組み合わせられる凹部５２が機器側の装着許容部として設けられている。したがって、電池パック２０ｄのスライドレール２４を機器本体１０ｃのガイド溝１４に挿入して電池パック２０ｄを機器本体１０ｃに装着すると、リブ３３ａが切り欠き部３４ａに入り込むとともに、突起部５１が凹部５２に組み合わされる。これにより、誤装着防止部２５は突出部１５に当接し、電池パック２０ｄは機器本体１０ｃに装着される。このときには、電池パック２０ｄの着脱操作部３１は突き当て部１８に突き当てられる。 The erroneous mounting prevention portion 25 of the battery pack 20d as the high-voltage power supply device shown in FIG. 7 is provided with a notch portion 34a having the same size as the battery pack 20c, and further, a rear end side portion of the attachment / detachment portion 22d. Is provided with a protrusion 51 as an erroneous mounting prevention portion (secondary erroneous mounting prevention portion) on the power supply side. The protruding portion 51 is inclined upward from the front end portion of the attachment / detachment portion 22d toward the rear end portion and protrudes from the attachment / detachment portion 22d. On the other hand, as shown in FIG. 3, the abutting portion 18 of the shared type device main body 10c is provided with a recess 52 in which the protrusion 51 is inserted and combined as a mounting allowable portion on the device side. Therefore, when the slide rail 24 of the battery pack 20d is inserted into the guide groove 14 of the device body 10c and the battery pack 20d is mounted on the device body 10c, the rib 33a enters the notch 34a and the protrusion 51 enters the recess 52. Combined. As a result, the erroneous mounting prevention portion 25 comes into contact with the protruding portion 15, and the battery pack 20d is mounted on the device main body 10c. At this time, the attachment / detachment operation portion 31 of the battery pack 20d is abutted against the abutting portion 18.

これに対し、電池パック２０ｄを機器本体１０ｂに装着しようとすると、図２（Ｂ）に示されるように、低電圧型の機器本体１０ｂの突き当て部１８には突起部５１が組み合わされる凹部が設けられていない。したがって、電池パック２０ｄの電源側の誤装着防止部としての突起部５１は、機器側の誤装着防止部（副誤装着防止部）としての突き当て部１８に当接し、高電圧型の電池パック２０ｄを機器本体１０ｂに装着することはできず、機器本体１０ｂへの誤装着が防止される。図１２は、電池パック２０ｄを機器本体１０ｂに装着しようとしたが、突起部５１が突き当て部１８に当接して、電池パック２０ｄが機器本体１０ｂに装着できない状態を示す。 On the other hand, when the battery pack 20d is attached to the device main body 10b, as shown in FIG. 2B, the abutting portion 18 of the low voltage type device main body 10b has a recess in which the protrusion 51 is combined. Not provided. Therefore, the protrusion 51 as the erroneous mounting prevention portion on the power supply side of the battery pack 20d abuts on the abutting portion 18 as the erroneous mounting prevention portion (secondary erroneous mounting prevention portion) on the device side, and the high voltage type battery pack The 20d cannot be attached to the device main body 10b, and erroneous attachment to the device main body 10b is prevented. FIG. 12 shows a state in which the battery pack 20d is attached to the device main body 10b, but the protrusion 51 abuts on the abutting portion 18 and the battery pack 20d cannot be attached to the device main body 10b.

なお、図３に示される凹部５２を突起部５１とし、図７に示される電池パック２０ｄの突起部５１を凹部５２としても良い。 The recess 52 shown in FIG. 3 may be a protrusion 51, and the protrusion 51 of the battery pack 20d shown in FIG. 7 may be a recess 52.

図１３は、電圧可変型電源装置の他の実施の形態としての１８Ｖまたは３６Ｖを選択的に出力可能な電源アダプタ２０ｅを示す斜視図である。この電源アダプタ２０ｅは、商用電源に接続されるコネクタ５４を有し、アダプタ本体５５内には商用電圧を所定の電圧に変換するトランスと、商用電流を直流に変換する整流回路とを有し、１８Ｖの低電圧と３６Ｖの高電圧とを選択的に出力する。電源アダプタ２０ｅの着脱部２２ｅは、電池パック２０ｃの着脱部２２ｃと同様の構造であり、誤装着防止部２５には、切り欠き部３４ａが設けられている。 FIG. 13 is a perspective view showing a power adapter 20e capable of selectively outputting 18V or 36V as another embodiment of the voltage variable power supply device. The power adapter 20e has a connector 54 connected to a commercial power supply, and has a transformer that converts a commercial voltage into a predetermined voltage and a rectifying circuit that converts a commercial current into a direct current in the adapter main body 55. A low voltage of 18V and a high voltage of 36V are selectively output. The attachment / detachment portion 22e of the power adapter 20e has the same structure as the attachment / detachment portion 22c of the battery pack 20c, and the erroneous attachment prevention portion 25 is provided with a notch portion 34a.

したがって、この電源アダプタ２０ｅは、電池パック２０ｃと同様に、図２（Ｂ）に示した低電圧型の機器本体１０ｂに装着することができるとともに、図３に示した共用型の機器本体１０ｃに装着することができる。 Therefore, the power adapter 20e can be attached to the low-voltage type device main body 10b shown in FIG. 2B and the shared type device main body 10c shown in FIG. 3 as well as the battery pack 20c. Can be installed.

図１４は、３６Ｖを出力する高電圧型電源装置としての電源アダプタ２０ｆを示す斜視図である。この電源アダプタ２０ｆは、商用電源に接続されるコネクタ５４を有し、アダプタ本体５５内には商用電圧を３６Ｖの電圧に変換するトランスと、直流に変換する整流回路とを有している。電源アダプタ２０ｆの着脱部２２ｆは、３６Ｖ専用の電池パック２０ｄの着脱部２２ｄと同様の構造であり、誤装着防止部２５には切り欠き部３４ａが設けられ、着脱部２２ｆの先端部には電源側の誤装着防止部としての突起部５１が設けられている。したがって、この電源アダプタ２０ｆは、電池パック２０ｄと同様に、図３に示した高電圧型の機器本体１０ｃに装着することができる。 FIG. 14 is a perspective view showing a power adapter 20f as a high voltage type power supply device that outputs 36 V. The power adapter 20f has a connector 54 connected to a commercial power source, and the adapter main body 55 has a transformer that converts a commercial voltage into a voltage of 36 V and a rectifier circuit that converts the commercial voltage into a direct current. The attachment / detachment portion 22f of the power adapter 20f has the same structure as the attachment / detachment portion 22d of the battery pack 20d dedicated to 36V, the erroneous attachment prevention portion 25 is provided with a notch portion 34a, and the tip portion of the attachment / detachment portion 22f has a power supply. A protrusion 51 is provided as a side erroneous mounting prevention portion. Therefore, the power adapter 20f can be attached to the high-voltage type device main body 10c shown in FIG. 3, similarly to the battery pack 20d.

低電圧電源装置として電池パック２０ｂおよび付加的な低電圧電源装置としての電池パック２０ａに代えて、それぞれ電源アダプタを適用することも可能である。 It is also possible to apply a power adapter instead of the battery pack 20b as the low voltage power supply and the battery pack 20a as the additional low voltage power supply .

図１５は、定格電圧３６Ｖの共用型の機器本体の他の実施の形態である機器本体１０ｇの電源装着部１１ｇの下面を示す斜視図である。図１６は図１５に示される機器本体１０ｇに装着される高電圧型電源装置としての３６Ｖ専用の電池パック２０ｇを示す斜視図である。 FIG. 15 is a perspective view showing the lower surface of the power supply mounting portion 11 g of the device body 10 g, which is another embodiment of the shared device body having a rated voltage of 36 V. FIG. 16 is a perspective view showing 20 g of a battery pack dedicated to 36 V as a high voltage type power supply device mounted on the device main body 10 g shown in FIG.

図１５に示されるように、共用型の機器本体１０ｇの一方のガイドレール１２には、機器本体１０ｃと同様に、機器側の誤装着防止用のリブ３３ａが設けられている。リブ３３ａはガイドレール１２から機器本体１０ｇの幅方向内方に突出しており、共用型の機器本体１０ｃのリブ３３ａと同様の長さ寸法である。機器本体１０ｇの先端部に設けられたケース片連結部１９には、機器本体１０ｇの前後方向に延びる摺動溝５６が形成されている。 As shown in FIG. 15, one guide rail 12 of the shared device body 10g is provided with a rib 33a for preventing erroneous mounting on the device side, similarly to the device body 10c. The rib 33a protrudes inward from the guide rail 12 in the width direction of the device body 10g, and has the same length dimension as the rib 33a of the shared device body 10c. A sliding groove 56 extending in the front-rear direction of the device body 10g is formed in the case piece connecting portion 19 provided at the tip of the device body 10g.

一方、電池パック２０ｇの誤装着防止部２５には、電池パック２０ｄと同様に、リブ３３ａが入り込む切り欠き部３４ａが設けられている。さらに、電池パック２０ｇの先端部には、電源側の誤接続防止部（副誤装着防止部）としての摺動突起５７が収容凹部３２内に突出して設けられ、摺動突起５７は機器本体１０ｇの前後方向に延びている。 On the other hand, the erroneous mounting prevention portion 25 of the battery pack 20g is provided with a notch portion 34a into which the rib 33a enters, similarly to the battery pack 20d. Further, at the tip of the battery pack 20 g, a sliding protrusion 57 as an erroneous connection prevention portion (secondary erroneous mounting prevention portion) on the power supply side is provided so as to project into the accommodating recess 32, and the sliding protrusion 57 is provided in the device body 10 g. Extends in the front-back direction of.

電池パック２０ｇを機器本体１０ｇに装着すると、リブ３３ａが切り欠き部３４ａに入り込み、摺動突起５７が摺動溝５６に入り込んで摺動溝５６に組み合わせられる。これにより、誤装着防止部２５は突出部１５に当接し、電池パック２０ｇの機器本体１０ｇに対する装着が完了する。これに対し、図１７および図１８に示されるように、電池パック２０ｇを機器本体１０ｂに装着しようとすると、摺動突起５７がケース片連結部１９に当接し、電池パック２０ｇを機器本体１０ｂに装着することはできない。さらに、電池パック２０ｇを機器本体１０ｄに装着しようとすると、摺動突起５７がケース片連結部１９の先端面に当接するので、電池パック２０ｇを機器本体１０ｄに装着することはできない。 When the battery pack 20 g is attached to the device main body 10 g, the rib 33a enters the notch 34a, and the sliding protrusion 57 enters the sliding groove 56 and is combined with the sliding groove 56. As a result, the erroneous mounting prevention portion 25 comes into contact with the protruding portion 15, and the mounting of the battery pack 20 g on the device body 10 g is completed. On the other hand, as shown in FIGS. 17 and 18, when the battery pack 20 g is to be attached to the device main body 10b, the sliding protrusion 57 comes into contact with the case piece connecting portion 19, and the battery pack 20 g is attached to the device main body 10b. It cannot be installed. Further, when the battery pack 20g is to be mounted on the device body 10d, the sliding projection 57 comes into contact with the tip surface of the case piece connecting portion 19, so that the battery pack 20g cannot be mounted on the device body 10d.

したがって、電池パック２０ｇは、共用型の機器本体１０ｇのみに装着される。電池パック２０ｄおよび電源アダプタ２０ｆが共用型の機器本体１０ｃのみに装着されるのと同様である。 Therefore, the battery pack 20 g is attached only to the shared device main body 10 g. It is the same as when the battery pack 20d and the power adapter 20f are attached only to the shared device main body 10c.

図１６は定格電圧３６Ｖの高電圧型電源装置としての高電圧専用の電池パック２０ｇを示すが、高電圧型電源装置としての電源アダプタとしても図１４に示される形状に代えて、図１６に示す形状としても良い。 FIG. 16 shows 20 g of a battery pack dedicated to high voltage as a high voltage type power supply device having a rated voltage of 36 V, but the power adapter as a high voltage type power supply device is also shown in FIG. 16 instead of the shape shown in FIG. The shape may be used.

上述のように、共用型の機器本体１０ｃには、電圧可変型電源装置としての電池パック２０ｃおよび電源アダプタ２０ｅと、高電圧型電源装置としての電池パック２０ｄおよび電源アダプタ２０ｆとのいずれかが選択的に装着され、共用型の機器本体１０ｃに装着される電圧可変型電源装置または高電圧型電源装置とにより電気機器が形成される。同様に、共用型の機器本体１０ｇには、電圧可変型電源装置としての電池パック２０ｃおよび電源アダプタ２０ｅと、高電圧型電源装置としての電池パック２０ｇとのいずれかが選択的に装着され、共用型の機器本体１０ｇに装着される電圧可変型電源装置または高電圧型電源装置とにより電気機器が形成される。 As described above, for the shared device main body 10c, either the battery pack 20c and the power adapter 20e as the voltage variable power supply device and the battery pack 20d and the power adapter 20f as the high voltage type power supply device are selected. An electric device is formed by a voltage-variable power supply device or a high-voltage power supply device, which is mounted on a shared device main body 10c. Similarly, either the battery pack 20c and the power adapter 20e as the voltage variable power supply device and the battery pack 20g as the high voltage type power supply device are selectively mounted and shared on the shared type device main body 10g. An electric device is formed by a voltage variable type power supply device or a high voltage type power supply device mounted on 10 g of a type device main body.

It has an erroneous mounting prevention portion 33a on the device side that abuts on the erroneous mounting prevention portion 25 on the side and prevents the battery pack 20b from contacting the protruding portion 15. Further, the device main body 10c has a recess 52 as a mounting allowance portion on the device side to be combined with the erroneous mounting prevention section 51 (secondary erroneous mounting prevention section) on the power supply side provided in the high voltage type power supply device.

共用型の機器本体１０ｇには、共用型の機器本体１０ｃの突出部１５と、機器側の誤装着防止部３３ａが設けられるとともに、機器本体１０ｃの凹部５２に代えて摺動溝５６が機器側の装着許容部として設けられている。 The shared device body 10g is provided with a protruding portion 15 of the shared device body 10c and an erroneous mounting prevention portion 33a on the device side, and a sliding groove 56 is provided on the device side instead of the recess 52 of the device body 10c. It is provided as a mounting allowable part of.

一方、電源装置は、少なくとも電圧可変型電源装置と高電圧型電源装置とを有し、電圧可変型電源装置としての電池パック２０ｃ、２０ｅは、低圧型の機器本体１０ｂと共用型の機器本体１０ｃのいずれにも選択的に装着される。高電圧型電源装置としての電池パック２０ｄと電源アダプタ２０ｆは、共用型の機器本体１０ｃに装着され、低電圧型の機器本体１０ｂには装着されない。高電圧型電源装置には、電源側の誤装着防止部２５が後端部に設けられ、さらに電源側の誤装着防止部５１が先端部に設けられている。同様に、高電圧型電源装置としての電池パック２０ｇは共用型の機器本体１０ｇに装着され、低電圧型の機器本体１０ｂには装着されない。 On the other hand, the power supply device has at least a variable voltage type power supply device and a high voltage type power supply device, and the battery packs 20c and 20e as the variable voltage type power supply device are the low voltage type device main body 10b and the shared type device main body 10c. It is selectively attached to any of the above. The battery pack 20d and the power adapter 20f as the high-voltage power supply device are attached to the shared device main body 10c, and are not attached to the low-voltage device main body 10b. The high-voltage power supply device is provided with an erroneous mounting prevention portion 25 on the power supply side at the rear end portion, and further, an erroneous mounting prevention portion 51 on the power supply side is provided at the front end portion. Similarly, the battery pack 20 g as the high voltage type power supply device is attached to the shared device main body 10 g, and is not attached to the low voltage type device main body 10b.

このように、電源装置着脱部と機器本体の電源装着部とを共通化しても、出力電圧が相違する多数の電源装置のうち適合しないものが機器本体に誤装着されることが防止され、機器本体を安全に作動させることができる。 In this way, even if the power supply attachment / detachment part and the power supply mounting part of the device body are shared, it is possible to prevent the device from being erroneously mounted on the device body among a large number of power supply devices having different output voltages. The main body can be operated safely.

図１９に示されるように、低電圧型電源装置と、電圧可変型電源装置と、低電圧型の機器本体と、共用型の機器本体とにより構成される電気機器グループからなる電気機器システムにおいては、低電圧型の機器本体１０ｂには低電圧型電源装置と、電圧可変型電源装置のいずれかが選択的に装着される。また、共用型の機器本体１０ｃ、１０ｇには、電圧可変型電源装置が装着され、低電圧型電源装置の誤装着は防止される。また、電気機器グループに高電圧型電源装置を付加すると、高電圧型電源装置は共用型の機器本体には装着することができるが、低電圧型の機器本体１０ｂに対する誤装着は防止される。さらに、機器本体１０ｄを備えた電気機器を付加すると、電圧可変型電源装置のみを装着することができる電気機器が電気機器グループに加えられる。 As shown in FIG. 19, in an electric device system consisting of an electric device group consisting of a low-voltage power supply device, a variable voltage power supply device, a low-voltage device body, and a shared device body. , A low-voltage type power supply device or a variable voltage type power supply device is selectively mounted on the low-voltage type device main body 10b.

The 36V type is used as the shared type equipment body and the high voltage dedicated type equipment body, and the 14.4V type is used as the additional low voltage. However, each rated voltage is an example, and if the reference voltage is the low voltage type and the higher voltage is the high voltage, the rated voltage is not limited to the above-mentioned values. ..
